As Paul Manafort prepares to stand trial in July for tax and bank fraud charges, Robert Mueller is asking the judge to issue 35 sets of subpoenas for witnesses to appear in court.

Bloomberg reports that Mueller sought the subpoenas from the judge who will preside over the case in Alexandria, VA. The filings reportedly state that Mueller did not say who he wants to appear during the trial, but he requested blank subpoenas so he could fill in the names later.
